STEAMER.

'Application filed May 10,

steamers for bread rolls for what is con ventionally known as hot dogs.

The object of the invention is to provide an efficient and serviceable steamer for rendering bread rolls more palatable and moreover that can be used for restoring stale rolls and in practice it has been found. that with 1 this steamer rolls that are even a week old may be refreshened without making them in any way soggy.

A further object of the invention is to provide a portable steamer that may be heated by any heat sourceelectric, gas, coal-oil stove et cetera and one that isparticularly suitable for use at highway refreshment booths where a-portablc steamer of this nature is largely needed.

Referring tothe drawings, Figure 1 is a side elevation of the steamer.

Figure 2 is a vertical section thereof.

Figure 3 is a plan view with the cover removed showing the-basket for holding the rolls and a steam-coil for steaming the same.

Figured is. a fragmentary vertical sectional view illustrating the steam coil connected up with the boiler;

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 2.

Like numerals of reference indicate corresponding parts in each of the figures throughout the drawings.

In the drawings, the reference numeral generally indicates the body of the device which is of cylindrical shape and has a flat bottom 11 for resting on a heater. The top of the body is open and the edge is beaded as at 12 in order to reinforce it. 13 is a shell of smaller girth than the body 10 and located therein. This shell has a bottom 14 spaced from the body bottom 11. The shell is considerably smaller in depth than the body and its top is flanged as at 15. This flange is annularly shaped and approaches closely to the inner surface of the body 10. A gasket 16 of suitable material is placed between the flange and the inner surface of the body and the flange is riveted or otherwise secured by means of securing elements 17 in order to form a water-tight joint. The shell together with the body 10 defines 1928. Serial no. 276,692.

a boilerllS. This boiler is provided with an inlet 19 shown in the form of an elbow which is closed by a cap 20 of the screw type. .It is. to be understoodthatin the.

event of running water being available the cap 20 may be dispensed with and the inlet connected with the running water. It will of course be necessary toemploy some form of valve asconventional to appliances of this kind in order that the water may be turned on and ofi".

The boiler may be provided with a water gauge 21 or any other fittings conventional to steamers. l y

22 a container of cylindrical shape and smaller diameter than the shell 13. The container is positioned centrally within the body lOand has its top 011 a level with the top thereof. The container has a floor 23 spaced tromthe shell bottom 14 and is supported in the body by an outwardly projecting-flange 24 that rests on the top edge 12 of the body. Theflange 24 is provided with'a circular series of holes 25. Between the containerand thebody is a circular hotairchamber26. I

27 is a receptacle shown in the, form of a reticulate basket such aswire mesh. This basketis of slightly smaller size than the container therein supported on legs 28. a

29 is the steam coil which is located in the vicinity of the top of the basket and consists of an approximately circular tube, preferably in the form of a slight spiral. This coil is placed between the container and the basket and has minute openings 30 arranged lengthwise so as to direct steam jets downwardly onto the rolls.

Referring particularly to Figure 4; one end of the coil is connected to a piping 31 that extends through the container and the cylindrical portion of the body and is then directed. downwardly to the boiler 18 communicating with the steam space thereof as at 32. The other end 33 of the coil is connected to a pipe 34.- that also ,extends through the container and the body 10 and has an. external petcock 35 by which it can be opened and closed. The coil slopes downwardly from its inlet end to the outlet end so that any steam condensing therein may be run off through the pet-cock 35.

36 is a lid of conical shape which has a downwardly turned edge 37 fitting over the beading 12 of 'the cylindrical body. The

apex is provided with a handle 38 by which it may be removed. 39 is a lining likewise ofconical shapeand spaced apart from the lid proper so asto provide a hot air compartment 40. The lower edge of the lining has a downwardly turned flange 41 that fits inside the container. This lining closes the top of the container and is rigidly aflixed to the lid proper by spacers as at 4:2, The hot air. space communicates withv the hot-air chamber 26 of the body through the openings/ in the flange 24. Bythis construction the interior of the container is completely surrounded by hotair space which servesto prevent condensation of the steam andithe attendant, formation of water within [the container which would injure the contents of the basket. 20.

In the use of this steamer, the boiler 18 is partly, filled with waterwhich is admitted through the inlet. 19 and upon being heated generates steam which rises and fills the space above the water. Steam, is conducted through the pipe3l to the coil 29 and escapes in the form of fine sprays or ets through the vapertures. 30 therein, being precipitated downwardly onto the rolls within the wire basket 27. The hot-air chambers surrounding the container prevents the condensation of thesteam as previously recounted.

.While this invention has been described as pa-rticularly applying to the heating of rolls c, it isequally susceptible ofbeing used for othersteaming purposes. alVhat we claim. is':

)1. A steamer of the class described comprisinga boiler for steam generation, a con- ,tainer, disposed thereover and externally heated thereby, a retieulate basket therein for containing articles to be steamed, a lid for closing the container, and a steam coil encircling the basket and having perforations for diffusing steam upon the contents thereof, said steam coil being connected to the boiler.

2. A steamer of the class described comprising a body, the lower part of which is divided oil into aboiler for steam generation, a container within the body substantially surrounded by hot air space, a reticnlate basket fitted within the container, a perforated steam coil encircling the basket, said steam coil being connected with the boiler, and a lid for closing the container.

3. A steamer of the class described comprising a hollow body provided with a flat bottom and an open top, a shell of lesser girth and depth located within the body, said shell having a bottom spaced from the body bottom, a flange projecting from the shell and secured to the body, said shell thus forminga boiler in the bottom portion of the body, a water inlet for the boiler, a container situated within the body and isolated from it and the shell by a hot air space, a perforated flange projecting from the container and resting upon the top of the body, a reticulate receptacle within the container, a perforated sloping coil encircling the receptacle, a pipe connecting an end of the coil to the boiler, and a double walled lid fitted to the body so that the space between the Walls communicates with the aforesaid perforations in the container flange.
